PEA CLEANER. i

Application led November 29, 1921. Serial No. 518,522.'

To all whom t may concern:

,Be it known that I, ANDREW JAcoBsEN,`a citizen of the United States,residing at Green Bay, in the county of Brown and State of Wisconsin,have invented certain new and useful Improvements in Pea Cleaners, ofwhich the following is a specification. The invention relates to a peacleaner, and

has for its primary object to provide a device, wherein the peas whendelivered from a vineriwill be directed onto a screen, whichagitatingthe screen being also novel.

A further object of the invention is the provision of a device of thischaracter, wherein the conveyor for they peas ,is disposed at aninclination, so that the peas will gravitate thereon onto the screen forthe separat-ion of the dirt from said peas, while the strawandstalkswill be carriedupwardly and discharged from the elevated point of theconveyor, thus it being seen that the straw, stalks, dirt, split peasand whole peas will be discharged at different points of the device forthe complete separation of the same.

A still further object of the invention is the provision of a device ofthis character, which is extremely simple in construction, thoroughlyreliable and eiiicient in operation, and. inexpensive in manufacture andinstallation.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts, as willbe hereinafter fully described, illustrated in the accompanying drawingand pointed out in the claims hereunto appended.

In the accompanying drawing:

' into the ncontainer therefor, the manner of Figure l, is a top planview of the device constructed in accordance with the invention.

Figure 2, is a fragmentary vertical sectional elevation.

Figure 3, is a view similar to Figure 2, on an enlarged scale.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, l, designates generally theconveyor, which in this instance, is in the form of an endless belt,preferably made from canvas or fabric of any suitable material, thelatter being trained over spaced parallel rollers 8, having theirjournals supported in any desirable way, so that one of the rollers 8,will be elevated relative to the other, whereby the c0nveyor will beinclined in one direction, as shown in Figures 2 and 3, of the drawing.These rollers 8, are preferably of squared formation in cross section,for a purpose as will be hereinafter described.

` Located adjacent to the lowermost roller 8, supporting the conveyor l,but spaced therefrom the desired distance is a container 4, in the formof a box open at its top through which peas-are discharged after thecleaning thereof, the container being designed to receive the peas whencleaned.

Bridging the space between the conveyor l, and the container 1i, is ascreen 2, preferably of the construction shown in Figure l, of thedrawing. The perforated portion 5, of this screen 2, extends over adistance of the open top of the container t, and has fixed thereto atopposite corners brackets 7 which are pivoted to the end of the saidcontainer 4, so that the screen can be swung up and down in a mannerpresently described.

On the free longitudinal edge of the screen 2, next to the conveyor l,is a series of hinged deiiectors 3, which are adapted to ride upon theconveyor l, during the travelling movement thereof in the direction ofthe arrows shown in Figures 1, 2 and 3, of the drawing.

Mounted on the ends of the lowerniost roller 8, are trips 6, which areadapted to engage with the free longitudinal edge of the screen 2, so asto intermittently agitata the saine when the conveyor is operating, todisplace the peas when delivered onto the screen from the said conveyorand thus cause the dirtand other foreign matter to be sifted throughsaid screen to the outside of the container,

while the whole peas will pass onto the portion 5, of the screen anddischarge into the container 4;. The screen 2, normally rests upon theside wall of the container 4, that is to say, the wall beneath saidscreen, as shown in Figure 3, of the drawing.

When the conveyor l, is operating the trips 6, on contact with thescreen 2. will lift it upwardly as shown in Figure 2, unt-il the saidtrips have passed the screen when the same will again drop or becomelowered to the position shown in Figure 3, of the drawing, and in thismanner the said screen will be intermittently agit-atedfor the separation of the peas and dirt thereon to assure the discharge of the peasinto the container 4f, and the dirt outside ofthe same V Thecross-sectional squared formation of the rollers 8, serves to keep thebelt l, taut and the lowermost roller active upon the defiectors 3, todirect the peas from the conveyor l onto the screen 2, as the saidpeasand dirt gravitate on said conveyor. The vine, straw or stalk .which aredelivered from the viner with the peas are carried upwardly of saidconveyor when dropped thereon, so that the said vines, straw and stalksare discharged from the elevated end t of the conveyor.

Split peas passed upon the screen 2, will discharge therethrough with`thef dirt outside of the container il, thus it being seen that thevines, straw or stalks will be discharged at one point, the dirt andsplit peas at another point and the whole peas at another point of thedevice, when the same is in operation.

From the foregoing it is thought that the construction and manner ofope-ration of the device will be clearly understood, and therefore a`more extended explanation has been omitted. However, changes,variations and modifications may be made in the device without departingfrom the spirit of the invention or sacricing any of its advantages, asfall properly within the scope of the claims hereunto appended..

l/Vhat is claimed is:

l. The combination with a container have ing an open top, of a screenextendedover a portion of the; open top of the container and swinginglyconnected to the ends thereof, an inclined conveyor adjacent tothe'container, and means operative with the conveyor for tripping thescreen to agitate the same. i t

2. The combination with a container hav-y ing an open top, of a screenpivotally connected with the ends of the container and extending over aportion of the open top of the same to normally rest upon one sidewallof said container, a conveyor in close proximity to the screen andinclined in the direction of the same, means operative with the conveyorfor tripping the screen to agitate the same, and deflector plates hingedto the screen and bridging the space between the latter and theconveyor.`

3. The combination with a container having an open top, of a screenpivotally connected with the ends of the container and extending over aportion of the open top thereof to normally rest uponl one side wall lofsaid container, a conveyor` in close proximity to the screen andinclined in the direction of the same, means operative with the conveyorfor tripping the screen to agitate the same, and deflector plates hingedto the screen at its edge adjacent to the con veyor and bridging thespace between it and the, screen, the plates being ink contact with saidconveyor. l, i

In testimony whereof I' have affixed my hand this 29th day'of Oct.192,1.A
